[原创自研]FlashSwirl 闪旋，一款高性能的对称加密算法库

FlashSwirl 闪旋，一款高性能的对称加密算法库，提供流加密、AEAD认证加密、HASH、HMAC、HKDF、PBKDF2

概述
由风之暇想研究的对称加密算法，基于ARX（Add-Rotate-XOR）结构设计，灵感来源于ChaCha20；加密库提供流加密、AEAD认证加密、HASH、HMAC、HKDF密钥派生、PBKDF2密钥派生的密码学功能。
✨ 特性

多种加密模式：支持流加密（Stream）和AEAD认证加密
高性能设计：批量处理、并行计算、内存池优化
跨平台支持：提供C++、Go、JavaScript三种语言代码

三种语言库调用说明
C++ 版本
使用示例：
#include "FlashSwirl.h"
#include <iostream>
#include <vector>

int main() {
// 准备密钥和Nonce

// ===== 1. 流加密 =====
FlashSwirl_EncryptBuffer(key, 32, nonce, 24, data.data(), data.size(), 20);
// data现在包含密文

FlashSwirl_DecryptBuffer(key, 32, nonce, 24, data.data(), data.size(), 20);
// data现在恢复为明文

// ===== 2. AEAD认证加密 =====
uint8_t plaintext[] = "Secret message";
uint8_t ciphertext[256];
int outLen = sizeof(ciphertext);
uint8_t ad[] = "additional-data";

FlashSwirl_EncryptAEADBuffer(key, 32, nonce, 24,
plaintext, sizeof(plaintext)-1,
ciphertext, &outLen, ad, sizeof(ad)-1, 20);

uint8_t decrypted[256];
int plainLen = sizeof(decrypted);
FlashSwirl_DecryptAEADBuffer(key, 32, nonce, 24,
ciphertext, outLen,
decrypted, &plainLen, ad, sizeof(ad)-1, 20);

// ===== 3. HASH =====
const char* message = "Hello, FlashSwirl!";
uint8_t hash[32];
FlashSwirl_Hash((const uint8_t*)message, strlen(message), 20, hash);

// ===== 4. HMAC =====
uint8_t hmacKey[] = "secret-key";
uint8_t hmacOut[32];
FlashSwirl_HMAC(hmacKey, sizeof(hmacKey)-1,
(const uint8_t*)message, strlen(message),
20, hmacOut);

// ===== 5. HKDF密钥派生 =====
uint8_t info[] = "my-app";
uint8_t derivedKey[32];
FlashSwirl_HKDF(masterKey, 32, salt, 32, info, sizeof(info)-1, 32, 20, derivedKey);

// ===== 6. PBKDF2密钥派生 =====
const char* password = "user-password";
uint8_t pbkdf2Salt[] = "random-salt";
uint8_t keyFromPassword[32];
FlashSwirl_PBKDF2((const uint8_t*)password, strlen(password),
pbkdf2Salt, sizeof(pbkdf2Salt)-1,
10000, 32, 20, keyFromPassword);

return 0;

"FlashSwirl"

func main() {
// 准备密钥和Nonce
key := make([]byte, 32)
nonce := make([]byte, 24)
rand.Read(key)
rand.Read(nonce)

// ===== 1. 流加密 =====
plaintext := []byte("Secret message")
var encrypted bytes.Buffer
FlashSwirl.Encrypt(key, nonce, bytes.NewReader(plaintext), &encrypted, 20)

var decrypted bytes.Buffer
FlashSwirl.Decrypt(key, nonce, &encrypted, &decrypted, 20)
fmt.Printf("Decrypted: %s\n", decrypted.Bytes())

// ===== 2. AEAD认证加密 =====
var aeadEncrypted bytes.Buffer
additionalData := []byte("context info")
FlashSwirl.EncryptAEAD(key, nonce, bytes.NewReader(plaintext), &aeadEncrypted, additionalData, 20
